Can you provide a minimal reproduce? Because it worked for me, I tested it in my android with code below:

https://facebook.github.io/react-native/docs/modal

I just doing

render() {
    return (
      <View style={{ alignItems: 'center', justifyContent: 'center', marginTop: 22, height: '100%', backgroundColor: 'white' }}>
       
        <Modal
          animationType="slide"
          transparent={false}
          visible={this.state.modalVisible}
          onRequestClose={() => {
            Alert.alert('Modal has been closed.');
          }}>
          <View style={{ marginTop: 22, alignItems: 'center', }}>
            <View>
              <Text style={{color:'black'}}>Hello World!</Text>

              <TouchableHighlight
                onPress={() => {
                  this.setModalVisible(!this.state.modalVisible);
                }}>
                <Text style={{ color:'black' }}>Hide Modal</Text>
              </TouchableHighlight>
            </View>
          </View>
        </Modal> 
        <TouchableHighlight
          onPress={() => {
            this.setModalVisible(true);
          }}>
          <Text style={{ color:'black' }}>Show Modal</Text>
        </TouchableHighlight>
      </View>
    );
